I'll admit it - I used to wing my buffet pricing and wonder why my profits kept shrinking. You calculate the cost price of a lunch buffet by adding up all ingredients per person, but many caterers just estimate this and end up losing money on larger orders. Here's how to nail down a profitable price for business lunches.
What's included in the cost price of a buffet?
With a lunch buffet, you don't just account for the food. Packaging, transport, and staff are also part of your cost price.
- Ingredients: all products that go on the buffet
- Packaging: chafing dishes, napkins, cutlery
- Transport: fuel and delivery time
- Staff: setup, service, breakdown
Calculate ingredient costs per person
Start by calculating how much each dish costs per person. Add up all ingredients, including garnishes and sauces. From years of working in professional kitchens, I've learned that forgetting small items like condiments can kill your margins fast.
💡 Example buffet for 30 people:
- Rolls (2 per person): €1.20
- Soup (250ml per person): €0.80
- Salad (150g per person): €0.90
- Fruit (100g per person): €0.60
Ingredients per person: €3.50
Add packaging and extra costs
Don't forget the costs you incur to deliver and set up the buffet. Divide these by the number of people.
💡 Extra costs for 30 people:
- Packaging and tableware: €45 total = €1.50 per person
- Transport (round trip): €30 total = €1.00 per person
- Setup and service (2 hours): €60 total = €2.00 per person
Extra costs per person: €4.50
Calculate your total cost price
Add all costs together to get your cost price per person. This is what it actually costs you to serve one person.
Cost price per person = Ingredients + Packaging + Transport + Staff
💡 Total cost price calculation:
- Ingredients: €3.50
- Extra costs: €4.50
Cost price per person: €8.00
Determine your selling price with margin
Your cost price isn't your selling price. You need margin for profit and unexpected costs. For catering, 60-70% of the selling price for costs is standard.
Minimum selling price = Cost price / (Cost percentage / 100)
💡 Selling price calculation:
Cost price: €8.00 per person
Desired cost percentage: 65%
Minimum selling price: €8.00 / 0.65 = €12.31 per person
⚠️ Note:
Always factor in 10-15% extra people in your purchasing. With no-shows you'll have too much, with extra guests too little. Better to have leftovers than to run short.
Account for minimum orders
Small buffets are often not profitable due to fixed costs. Set a minimum number of people to cover your costs.
- Transport and setup cost the same for 10 or 50 people
- Below 20 people, catering often becomes unprofitable
- Charge a surcharge for small groups or set a minimum
⚠️ Note:
Check your purchasing prices regularly. Suppliers raise their prices, but many caterers don't adjust their selling prices. That eats into your margin.
How do you calculate the cost price of a lunch buffet? (step by step)
Create an ingredient list per person
Write down all dishes that will be on the buffet. Calculate how many grams or ml you need per person. Add up the costs of all ingredients.
Calculate packaging and transport
Add up all extra costs: tableware, chafing dishes, transport, setup. Divide this by the number of people to get the cost per person.
Determine your selling price with margin
Divide your total cost price by your desired cost percentage. For catering, 60-70% of the selling price for costs is standard.
✨ Pro tip
Review your buffet cost calculations every 6 weeks to catch supplier price increases early. I've seen caterers lose 15% margin simply because they didn't adjust prices after their suppliers raised theirs.

Frequently asked questions
How much margin should I calculate on a lunch buffet?
For catering, 30-40% profit margin is standard. That means your costs are 60-70% of your selling price. With higher margins you'll be too expensive for business lunches.
Should I include VAT in my cost price calculation?
No, always calculate without VAT. Your costs are excl. VAT and you calculate your selling price excl. VAT as well. Then you add 9% VAT for the final price.
What if fewer people show up than ordered?
Agree in advance that you charge based on the number of people ordered, not the number present. After all, you've purchased and prepared for that number.
